Název v původním jazyce

Microstructural evolution in Ti-10Al-1Zr-1Mo-1Nb alloy under thermomechanical treatment in β-region

Popis výsledku v původním jazyce

The influence of temperature and strain rate on microstructural evolution in near α-type Ti-10Al-1Zr-1Mo-1Nb alloy was studied under uniaxial compression in the β single-phase-region. Hot compression tests were conducted for up to 75% reduction at temperatures between 1273 K and 1333 K and strain rates between 0.01 sMINUS SIGN 1 and 5 sMINUS SIGN 1. The steady-state of the flow behavior revealed that dynamic recovery in the β single-phase was dominant in the microstructural evolution process, and few dynamically recrystallized grains were detected, except in the vicinity of the pre-existing β grain boundaries. Two types of configurations such as lamellar αL and acicular αAC microstructures were developed, which were consistent with the compressive deformation mechanism in the β-region. The αL microstructure consisted of α platelets that were developed via growth of a specific variant, whereas the αAC microstructure consisted of individual α platelets with a different variant in the prior-β matrix.
